I was strictly a melt and pour craft person until this year. I ALWAYS enjoyed my Melt and Pour creating. Melt and Pour soap is fun and easy. It doesn't require a lot of extra material. I've showed 10 year olds how to make m & p soap. I use SFIC Shea Butter or Aloe bases. I, also, really liked Stephenson's triple butter base. My friends either LOVED or HATED the Stephenson triple butter because it feels like you can't totally rinse the oils off.
The most common complaint about melt and pour bases is that they don't last long in the shower.
After year's of drooling of some of the swirls that CP soap is famous for, I decided to branch into that domain this year. Suddenly, I had to deal with issues like how well a fragrance lasts (sticks) in the soap. Let's not forget that there is the aspect that the fragrance can make the soap batter misbehave - rice, sieze, or accelerate. In addition to fragrance issues, there is the storage aspect during the 4 to 6 week cure. With CP soap, you have to be very careful during the soap making process so that you don't get injured from the lye. The benefit to CP soap is that it produces a harder bar of soap that lasts longer in the shower.
With m & p, you can easily create A bar of soap in the morning and enjoy it 24 hours later. With CP soap, it is really hard to make batches smaller than a pound and it is 4 to 6 weeks before you can reap benefits of your work.
